Claude Usage TUI

An independent, local-only terminal viewer for Claude Code token activity. It draws daily, weekly, and cumulative graphs and always reports how much of the calendar is backed by exact turns versus historical aggregate allocation.

Install

With uv:

uv tool install claude-usage-tui

Or with pipx:

pipx install claude-usage-tui

For development, install from a checkout:

uv tool install .

The runtime uses only the Python standard library and sends no data anywhere.

Use

# Open the interactive daily graph
claude-usage

# Open a particular view
claude-usage weekly
claude-usage cumulative

# Compatibility with the earlier prototype
claude-usage usage daily

# Show exactly how much is observed and reconstructed
claude-usage audit

# Refresh only the local JSONL index
claude-usage scan

Inside the TUI, use the arrow keys or d, w, and c to change views. Press q to exit. Add --once --no-color for a non-interactive plain-text render.

Where the numbers come from

The tool never queries Anthropic and does not scrape CodexBar. It reads files already maintained on your machine:

The index deliberately retains already parsed turns if Claude Code later removes their JSONL file. It contains token metadata only, not prompts, responses, filenames from source code, or transcript content.

Exact versus reconstructed

For each model, the tool first sums exact indexed turns. If Claude's local modelUsage total is larger, the difference is known to exist but its original cache-token timestamps are no longer available. The tool distributes only that difference across Claude's retained dailyModelTokens activity dates.

Consequently:

• Lifetime reconciles to the newest available local per-model total.
• Exact JSONL dates keep their exact token counts.
• Historical daily, weekly, peak, and streak values are approximate wherever an aggregate-only difference exists; the TUI marks these with ≈.
• claude-usage audit prints exact and allocated totals globally and per model.
• Missing dates cannot be invented. If neither JSONL nor stats-cache.json covers a period, the tool has no evidence for that period.

This is token activity, including cache reads and cache creation. It is not the percentage of a Claude subscription quota, an Anthropic invoice, or a server-authoritative account history. Subscription windows and dynamic limits are not present in these local history files.

Privacy and storage

• All parsing and rendering happens locally.
• There are no runtime dependencies, telemetry, network requests, or API keys.
• The database defaults to ~/.claude/usage-tui.db and can be overridden with CLAUDE_USAGE_TUI_DB or --db.
• CLAUDE_STATS_CACHE can point at a different stats cache.
• Use --projects-dir PATH to scan one non-default transcript directory.

Project scope and provenance

This is a focused implementation containing only:

• a minimal incremental JSONL collector;
• source reconciliation and accuracy reporting;
• the terminal renderer and command dispatcher;
• tests and packaging.

It does not include the browser dashboard, pricing model, Docker setup, VS Code extension, or general session analytics from phuryn/claude-usage. That project informed the early prototype and is credited, with its MIT notice, in THIRD_PARTY_NOTICES.md. The visual presentation is inspired by the Codex token activity interface; no Codex source or assets are included.

Development

python3 -m unittest discover -s tests -v
python3 -m py_compile cli.py collector.py usage_tui.py

Releases use PyPI Trusted Publishing: a signed vX.Y.Z tag must exactly match collector.VERSION. GitHub Actions tests and builds the distributions, uploads them to PyPI through short-lived OIDC credentials, and then creates the GitHub Release. See RELEASING.md.
